“…In the South Caspian segment of the territory under consideration, up to the Bathonian, there was a relict Paleotethis zone, which to the east up to the present is characterized by the subcontinental and suboceanic crust of the central part of the Kura depression and the South Caspian basin. Much attention in the process of research was paid to the relationship of constructive and destructive processes taking place in the region [10]. And, if the primacy of the constructive process is characteristic of the South Caspian segment, then in the Black Sea segment these processes shifted each other in time, creating conditions for both the formation of the continental crust and its destruction.…”

The Black Sea-South Caspian megadepression is a vast region includes large geological structures developed during the Meso-Cenozoic time and have both a single development history and a different one. Based on the chemistry of volcanic rocks and seismic data, to determine the genesis of the geological structures that make up the Black Sea-South Caspian megadepression, its evolution and the presence of minerals an attempt was made. Large modern geostructural elements, such as the Riony, Kura, West Turkmenian, Black Sea and South Caspian depressions, which are part of the megadepression, have united into a single whole as a result of processes taking place on the margin Tethys Ocean. Based on the analysis of volcanic rocks buried under Cenozoic sediments, the picture of the ancient ocean margin development and its subsequent history were modeled. Favorable conditions for the generation and accumulation of hydrocarbons, formed as a result of all processes, led to the fact the entire Black Sea-South Caspian megadepression has a huge reserve of these minerals.

“…The primary uplift in the Muradkhanly area is due to an effusive complex of Upper Cretaceous age rocks. This uplift is covered with Paleogene-Miocene sediments, which in turn are covered with a Pliocene-Anthropogenic complex that was not involved in folding [Alizada et al, 2013;Akhmedov, Aghayeva, 2022;Kerimova, Aliyev, 2022;Kerimova, 2023].…”

The presence of oil accumulations in igneous rocks has been known for quite a long time. Geologists estimate that oil reserves in eruptive and weathered metamorphic rocks reach 1 % of the world’s proven oil reserves. At the Shaimskoye field (Western Siberia), oil is found in the weathered granites of the basement. Oil has been found in eruptive rocks in Texas (USA) fields, the most famous of which is the Litton Springs field. Oil is found in metamorphosed shales in the western part of the Los Angeles basin, the porosity of which is caused by the development of cracks in the roof of crystalline shales. Petroleum is extracted from serpentinites in Cuba. Basic igneous rocks contain petroleum at the Ferbro field in Mexico.At the Khukhrinsky gas field, which islocated at the north-western end of the Dnieper-Donets depression, the crystalline basement rocks are oil and gas bearing, from which commercial hydrocarbon inflows have been obtained. In the White Tiger field (Bach Ho), located on the southern shelf of Vietnam, commercial oil accumulations are also found in crystalline basement rocks. At the Muradkhanli field in Azerbaijan, the industrial accumulation of petroleum belongs to the igneous rocks of the Upper Cretaceous age. The natural oil and gas reservoir of the Muradkhanli field is confined to the erosion zone of the upper part of the section of these rocks. This work aims to determine the reservoir properties of the rocks of the Muradkhanli deposit, which belong to igneous rocks, in different ways. The method of estimation of final oil recovery of complex structure reservoirs was proposed for useful capacity and oil recovery of homogeneous media; different variants of the volumetric method were used for reservoirs with complex structures of pore space filling a complex and heterogeneous natural reservoir; values of hydrocarbon reserves of increased and secondary capacity were calculated for the study interval; distributions of oil reserves with right-sided asymmetry, where Mo<Me<X, were presented; it was determined that in effusive cores oil saturation and fluid filtration are caused by tectonic fracturing and cavernousness. Permeability varies in a wide range: 0.73·10–15—1.31·10–15 m2; the largest specific fraction of crack density is in the range 0—0.1 cm/cm2, the average value is 0.29 cm/cm2, with crack depth they decrease from 0.9 to 0.1 cm/cm2. The studies have shown that the natural reservoir of oil and gas in the Muradhanli field is associated with the erosion zone of the upper part of the igneous rock section.
